Jules Bastien-Lepage is high in key: pale, luminous, and filled with optical air. Temperature is cool-dominant, with blue and green families claiming the largest areas. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. #98A7BD at 30.7% of the palette: an overwhelming presence that pulls all other colours into its gravitational field. The saturated accent, #745343, registers at 2.4% - sparse enough to feel like a deliberate surprise. 44 units of value spread create a palette that is varied but unified - contrast in the service of harmony. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Jules Bastien-Lepage's palette 1 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
